Hardware Caching

Hardware caching is a technique used in computers to speed up data access. It involves storing frequently used information in small, fast memory areas called caches, which are closer to the processor. When the CPU needs data, it first checks the cache. If the data is there (a cache hit), it can be retrieved quickly, improving performance. If not (a cache miss), it fetches from the larger, slower main memory, then temporarily stores it in the cache for future use. This process reduces delays and enhances the overall efficiency of the system.
